7. Explain the steps involved in executing a C program. *
Execution of C Program:
1. Creating the Program:
The program should be typed in the Turbo C editor and saved.
This program is called source program.
Source Program – General Form:
filename.c
Example: Sample.c
2. Compiling the Program:
Compilation is the process of converting the source program into machine language program (object
program).
The source program should be compiled using the Compile option in the Turbo C editor.
During compilation, source program is converted into object program.
Object Program - General Form:
filename.obj
Example: Sample.obj
3. Linking and Running the Program:
Linking is the process of connecting header files with the program.
Linking converts object program into executable program.
Executable Program – General Form:
filename.exe
Example: Sample.exe
Executable program should be run using the Run option in the Turbo C editor.
